superheterodyne ASK receiver module

superheterodyne ASK receiver module
Product Detailed
It's used in low power wireless application occasion .

KST-RX902 Wireless Superheterodyne receiver module

KST-RX211 is superheterodyne ASK receiver module with excellent function .It’s used in low power wireless application occasion . The design is adopted Single superheterodyne receive chips, VCO and FLL is inside in it, Provided accurate local

Oscillation signal ,good stability ,high sensibility ,low power ,widely used in all kinds of big interference,badly environment’s occasion .

A. Technical  parameter :

   1 .operating voltage  : 5VDC

   2 .operating current : 11Ma

   3 .operating frequency  :433.92MHZ

   4 .modulation: ASK superheterodyne

   5 .receive sensibility:-110db

   6 .storage temperature :-40--+85 degree Celsius

B. Application:

   1 .Car alarm system

   2 .Intelligent Home use security

   3 .Wireless keyboard , mouse

   4 .Toy remote control

C. Size:

  20.20mm*13.15mm (L*W)

D. Characteristic

   1. ASK receiver module

   2. non-noise wave , anti-motor and anti-disturb receiver module

   3. Past FCC/CE certification

E.  Notes :

   1.The Antenna is using soft wire or other hard metal(like trolley antenna),The length is can’t be too long and too short, Otherwise it will interference the receive distance. If it uses the soft wire, please use it by straight , avoid to near the metal things.

   2. The requirement on power and voltage is stability and low ripple coefficient . should be multi-stage filter (as add Beads, Inductance, Capacitance and so on)

    3. Suggested MCU clock frequency should below 4MHZ if it uses with Single machine, otherwise the high harmonic crystal will influence on communication distance.
